Happy MLK, The ventilation motor died in my '88 so I replaced it Saturday with an NOS Delco. Installation into that tight spot went well. However, upon moving the big wrapped wiring harness between the engine and the firewall out of the way, the thin plastic vacuum tubing for the HVAC system broke, and I cannot find the other end that I need to reconnect it to! The end from the splitter just aft of the check valve is visible, but where it broke off from is not, at least with my poor eyesight. I suspect like in my Camaros that this vacuum tubing is enclosed in the big wire harness for protection, and that the other end has receded into the harness. Before I slice that harness to fish it out, I just want to make sure i am not looking in the wrong area for the tubing that runs thru the firewall to control the vent settings. Cruise is hooked up so it is not that, and my HVAC only runs with both the heater and defrost working in default. At least it is warm in the car! Thanks for any advice as usual, Mike
